docs: def Q_weir_rectangular_full_Kindsvater_Carter(h1, h2, b):
      r'''Calculates the flow rate across a full-channel rectangular weir from
      the height of the liquid above the crest of the weir, the liquid depth
      beneath it, and the width of the channel. Model from [1]_ as reproduced in
      [2]_.
  
      Flow rate is given by:
  
      .. math::
          Q = \frac{2}{3}\sqrt{2}\left(0.602 + 0.0832\frac{h_1}{h_2}\right)
          b\sqrt{g} (h_1 +0.00125)^{1.5}
  
      Parameters
      ----------
      h1 : float
          Height of the fluid above the crest of the weir [m]
      h2 : float
          Height of the fluid below the crest of the weir [m]
      b : float
          Width of the channel section [m]
  
      Returns
      -------
      Q : float
          Volumetric flow rate across the weir [m^3/s]
  
      Notes
      -----
      The following limits apply to the use of this equation:
  
      h1 > 0.03 m
      b > 0.15 m
      h2 > 0.1 m
      h1/h2 < 2
